Arizona Taxes for Tax Year 2025 (Filed 2026): Rates, Phoenix Sales Tax, Property Tax

 

Arizona taxes can feel simpler than many states because the state uses a flat individual income tax rate for Tax Year 2025 (filed in 2026).
Still, real life gets complicated fast once you mix in withholding, estimated payments, local Transaction Privilege Tax (often called sales tax),
and property tax rules that vary by county and city.

This guide focuses on the taxes most Arizona residents and small businesses run into: state income tax, Phoenix-area and statewide sales tax concepts,
use tax for online purchases, and property tax basics, with practical examples placed next to the topics where you need them.

Arizona State Income Tax Basics

Arizona generally starts your state income tax calculation with your federal income figure, then applies Arizona-specific additions and subtractions,
and then applies either the Arizona standard deduction or your Arizona itemized deductions.
After that, Arizona applies a flat tax rate.

Most full-year residents file an Arizona resident return.
Part-year residents and nonresidents typically file a different Arizona return to report Arizona-source income and the portion of income earned while living in Arizona.

 

Who Must File an Arizona Return

You may need to file an Arizona return if you were an Arizona resident for any part of the year, or if you had income from Arizona sources.
Common Arizona-source income includes wages for work performed in Arizona, Arizona business income, and income from Arizona rental property.

If you moved into or out of Arizona during Tax Year 2025, you typically file as a part-year resident and allocate income based on the portion tied to Arizona.

 

Example 1

Lina moved to Arizona on July 1, 2025. She earned $90,000 total wages in 2025, with $40,000 earned after the move.
A typical part-year approach is that the Arizona return focuses on the period of Arizona residency and Arizona-source income.
In Lina’s case, the $40,000 earned after moving to Arizona is the clearest chunk to treat as Arizona-taxable wages, before considering any other Arizona-source items.

Practical tip: Keep a simple timeline, your move date, paystubs around the move, and any documentation showing where the work was performed,
especially if you had remote work, travel, or multiple states involved.

 

Income Tax Rate and Standard Deduction

Flat Income Tax Rate

Arizona uses a flat individual income tax rate for all income levels and filing statuses, which means there are no bracket breakpoints to calculate.

 

Arizona Standard Deduction Amounts

Arizona standard deduction amounts are:

  • Single, or married filing separately: $15,750
  • Married filing jointly: $31,500
  • Head of household: $23,625

Example 2

Jordan is a full-year Arizona resident with $60,000 of income and no Arizona-specific additions or subtractions.
Jordan claims the $15,750 Arizona standard deduction.

Arizona taxable income: $60,000 minus $15,750 equals $44,250.
Arizona tax at a flat 2.5%: $44,250 times 0.025 equals $1,106.25.

If Jordan had $1,200 withheld for Arizona during 2025, Jordan would expect a refund of about $93.75, assuming no other taxes or credits apply.

 

Example 3

A married couple filing jointly has $120,000 of combined income and no Arizona-specific additions or subtractions.
They use the $31,500 Arizona standard deduction.

Arizona taxable income: $120,000 minus $31,500 equals $88,500.
Arizona tax at 2.5%: $88,500 times 0.025 equals $2,212.50.

 

Common Arizona Additions and Subtractions

Arizona tax law can require certain income items to be added back, and it can allow certain subtractions that reduce Arizona taxable income.
The exact list depends on your situation, including retirement income, interest, and certain other adjustments.

Practical approach: If your federal return has unusual income types, large retirement distributions, or multi-state income,
review the Arizona return’s additions and subtractions section carefully before assuming your Arizona taxable income equals your federal taxable income.

 

Arizona Tax Credits Worth Knowing

Arizona offers several credits that can reduce your state tax bill.
Credits are especially important in a flat-tax state because they can reduce your tax dollar-for-dollar, subject to each credit’s rules.

One commonly discussed credit category is the credit for contributions to private school tuition organizations, which has inflation-adjusted limits for Tax Year 2025.

 

Withholding and Estimated Payments

Withholding From Paychecks

If you are an employee, Arizona tax is commonly paid throughout the year through withholding.
Underwithholding can lead to an unexpected balance due at filing time.

 

Estimated Payments for Self-Employed Income, Side Income, and Underwithholding

If you have income not covered by withholding, such as self-employment income, investment income, or rental income,
you may need to make estimated tax payments during Tax Year 2025.

For many calendar-year filers, Arizona estimated payment due dates are aligned to quarterly timing.
Typical dates include April 15, June 15, September 15, and January 15, with adjustments when a date falls on a weekend or holiday.

 

Example 4

Maya expects $40,000 of net self-employment income for 2025 and has no Arizona withholding.
A rough starting point for Arizona income tax alone is 2.5% of the income after deductions.

If Maya’s Arizona taxable income ended up near $30,000 after deductions and adjustments, a rough Arizona tax estimate would be $30,000 times 0.025 equals $750.
Maya could plan to pay this across estimated payments during 2025, then true-up the final amount when filing in 2026.

Practical tip: Keep separate buckets for federal tax, Arizona income tax, and self-employment taxes, since the largest surprise is usually not the Arizona portion.

 

How and When to File

Key Filing Deadline

Your Arizona individual income tax return for Tax Year 2025 is due by midnight on April 15, 2026.
If you file under a valid extension, the extended due date to file is October 15, 2026.

 

Extensions and Payments

An extension typically gives you more time to file, not more time to pay.
If you expect to owe, plan to pay by the original due date to reduce penalties and interest.

You can often pay online without creating an account through AZTaxes.gov.

 

Which Arizona Forms Are Common

Many full-year residents file an Arizona resident income tax return.
Part-year residents and nonresidents generally use a different Arizona return designed for allocating Arizona income.
If your situation is simple, Arizona also offers simplified return options in some cases.

 

Arizona Sales Tax: Transaction Privilege Tax (TPT)

Arizona’s “sales tax” is commonly referred to as Transaction Privilege Tax (TPT).
The tax is imposed on the seller under Arizona law, but it is typically passed on to consumers at the register.

The state TPT rate is 5.6%, and cities and counties can add their own rates.
That is why the total rate you see in Phoenix or any other city can be higher than the state rate.

Rates vary by location and sometimes by business classification, so the most reliable method is to look up the rate for the exact address where the sale occurs.

 

Example 5

Suppose you buy a taxable item priced at $200.
If your combined rate is 8.6% in your location, the tax would be $200 times 0.086 equals $17.20, and the total would be $217.20.

This is an example only. Your combined rate depends on the exact Arizona address and the type of sale.

 

Use Tax on Out-of-State and Online Purchases

If you buy taxable goods from an out-of-state or online seller and no Arizona tax is charged, Arizona may still require use tax.
The state use tax rate is the same as the state TPT rate, currently 5.6%, and cities can also assess use tax through TPT.

 

Example 6

Alex buys a $1,000 laptop online and the seller does not charge Arizona tax.
The state use tax portion at 5.6% would be $1,000 times 0.056 equals $56.

Depending on Alex’s city, additional local use tax may apply.

 

Arizona Property Tax Basics

Arizona property tax is set and collected locally, and it is not a flat statewide percentage.
Your tax bill depends on how your property is valued and classified, what exemptions apply, and what rates are set by the taxing jurisdictions in your area.

A common high-level flow is:
determine a valuation, apply an assessment ratio to reach assessed value, subtract any exemptions to reach net assessed value, then apply tax rates to compute the bill.

 

Senior Valuation Protection Option

Arizona has a Senior Property Valuation Protection Option, often called the “senior freeze,” which is a valuation relief program that eligible homeowners apply for through the county assessor process.
It generally focuses on freezing valuation for a period, not guaranteeing the final tax bill stays unchanged, since rates can still change.

 

Example 7

If a home has a net assessed value of $60,000 and the total combined local tax rate applied to that value is 1.20%,
a simple estimate is $60,000 times 0.012 equals $720 for the year.

This is a rough estimate only. Arizona property tax bills vary by location, voter-approved items, exemptions, and valuation changes.

 

Estate and Inheritance Taxes

Arizona does not impose a state estate tax, and Arizona does not impose an inheritance tax.
Estate planning may still involve federal estate tax rules, depending on the size of the estate.

 

Business Taxes in Arizona

Self-Employed and Small Business Owners

Many small businesses interact with Arizona taxes through a mix of individual income tax (for pass-through income),
withholding for employees, and TPT licensing and filing if they sell taxable goods or services that fall under taxable classifications.

 

Corporations

C corporations can owe Arizona corporate income tax, and businesses may have additional compliance requirements depending on nexus, payroll, and sales.

Practical tip: If you run a business in multiple Arizona cities, you may need to pay close attention to location-based TPT rates and city codes used for reporting.
